“Unnecessary” Spinal Surgery: A Review With Commentary

Department of Neurological Surgery, The Albert Einstein College of Medicine, Bronx, NY, USA

INTRODUCTION: Although one spine surgeon may decide that a patient needs surgery, another surgeon [e.g. a second opinion] might decide that surgery is “unnecessary”. Here we define “unnecessary surgery” as spinal surgery based upon “pain alone”. That is, the patient has no neurological deficit and no significant abnormal radiographic findings on dynamic X-rays, MR, and/or CT. Surgeons can, and do, debate whether it is appropriate to operate on patients with pain alone. To put this debate in context, however, we need to better understand the number of patients involved and the type of procedures recommended. In this prospective study performed over a one-year period, a single neurosurgeon documented the “unnecessary” lumbar and cervical surgeries planned by other spinal surgeons.

BACKGROUND: There are marked disparities in the frequency of spinal surgery performed within the United States over time, as well as across different geographic areas. One possible source of these disparities is the criteria for surgery.

METHODS: During a one-year period [November 2009-October 2010], the senior author, a neurosurgeon, saw 274 patients for cervical and lumbar spinal, office consultations. A patient was assigned to the “unnecessary surgery” group if they were told they needed spinal surgery by another surgeon, but exhibited pain alone without neurological deficits, and without significant abnormal radiographic findings [dynamic X-rays, MR scans, and/or CT scans].

CONCLUSIONS: During a one-year period, 47 [17.2%] of 274 spinal consultations seen by a single neurosurgeon were scheduled for “unnecessary surgery”.

Chiro.Org Editorial Commentary

I have a few, serious issues with the comments made in this article.

1. Yes, it’s interesting to know that 17.2% of back surgeries are unnecessary. BUT, what about the outcomes for the other 82.8% of the individuals who DO end up getting surgery? What about them???

A 2011 review in Spine Journal (the Bible of spinal surgery) reviewed records from 1,450 patients in the Ohio Bureau of Workers’ Compensation database, who had diagnoses of disc degeneration, disc herniation or radiculopathy, a nerve condition that causes tingling and weakness of the limbs.

Half of the patients received surgery to fuse two or more vertebrae in hopes of curing low back pain. The other half had no surgery, even though they had comparable diagnoses. After two years, only 26 percent of those who received surgery had actually returned to work. That’s compared to 67 percent of patients who didn’t have the surgery, even though they had the same exact diagnosis. This translates as a 74% failure rate for low back surgeries! It also means you are 257% more likely to go back to work IF YOU DON’T GET SURGERY THAN IF YOU DO.

“The study [1] provides clear evidence that for many patients, fusion surgeries designed to alleviate pain from degenerating discs don’t work”, says the study’s lead author Dr. Trang Nguyen, a researcher at the University of Cincinnati College of Medicine. [2]

Yes, the author does go on to decry operating on individuals with “major, overlapping, potentially life-threatening co-morbidities”

BUT

their idea of conservative treatment remains mired in the past, because it is still limited to anti-inflammatories, physical therapy and epidural steroids

I have to wonder WHY the author appears to be blissfully ignorant of the benefits of manipulative manual treatments, including chiropractic care, and the numerous guidelines and evidence reviews from medical groups from around the world that now support it:

A review in the January 2011 edition of European Spine Journal includes a brilliant review of “the effectiveness of pharmacological interventions [i.e., non-steroid anti-inflammatory drugs (NSAIDs), muscle relaxants, antidepressants, and opioids] for non-specific chronic low-back pain (LBP)”.

The researchers concluded that NSAIDs and opioids “seem to lead to a somewhat higher relief in pain on the short term, as compared to placebo” (aka no treatment at all!), “in patients with non-specific chronic low back pain, and that both types of medication show more adverse effects than placebo”. (What an elegant understatement that is!)

Surgery for non-specific CLBP cannot be recommended unless 2 years of all other recommended conservative treatments — including multidisciplinary approaches with combined programs of cognitive intervention and exercises — have failed

A lot of what’s considered “standard medical treatment” was listed as invasive treatments, that should NOT be recommended for non-specific CLBP.

That includes:

Bed restAcupunctureEpidural corticosteroidsIntradiscal injectionsIntra-articular (facet) steroid injectionsLocal facet nerve blocksTrigger point injectionsProlotherapyBotulinum toxinRadiofrequency facet denervationIntradiscal radiofrequency lesioningIntradiscal electrothermal therapyRadiofrequency lesioning of the dorsal root ganglionand Spinal cord stimulationOur Low Back Pain and Chronic Neck Pain pages list numerous other studies that suggest that spinal manipulation is highly effective for relieving spinal pain, and have been shown time and again to be more effective AND cost-effective than standard medical care.

I can’t say for sure how or why medical authors remain unaware of this massive volume of literature support for chiropractic and spinal manipulation. I do believe its in the best interests of our patients that chiropractors continue to share these materials with their local medical associates.
